Reflective-Formative 2nd order model/Effects of subdimension

Post by amoghta » Sun Apr 05, 2015 9:56 pm

I have attached an example of Reflective-Formative 2nd order model.
This model can be solved using two step approach and the relation between main constructs A, B, and C and easily be calculated.
But how would you know the effect of separate dimensions of these constructs (A1, A2, A3, B1, B2 and so on) on other constructs? (A, B, C)
Eg- I want to see the effect of A1 (subdimension of A) on B.

How would you tackle such situation in 2nd order formative constructs?

You must get a score of latent variables before estimating the model. Please read these terms of reference related.
To determine the effect of sub-dimensions of each variable to another variable only live view output "indirect effect". But because you want to use a two-step approach, the sub-dimensions will automatically disappear, so you can not see the effect.
